The Properties of Chemical Substances - dummies

2019-5-18 · When chemists study chemical substances, they examine two types of properties: chemical properties and physical properties. Some physical properties are extensive properties, properties that depend on the amount of matter present. Mass and volume are extensive properties. Intensive properties, however, don’t depend on the amount of matter present.
